Features

* a low-power consumption shutdown mode. Additionally, the LM4953 features an internal thermal shutdown protection mechanism. The LM4953 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4953 is unity-gain stable a

Applications

* When powered by a 3.6V supply, it is capable of forcing 12.6Vpp across a 2µF + 30Ω bridge-tied-load (BTL) with less than 1% THD+N. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4953 does not require
